2. Speaker • 林佑安 c9s@twitter, c9s@github • Web Developer • CPAN author for ~30 distributions. • 187 repos/projects on GitHub. • Perl programming since 2008. • PHP programming since 2011. Saturday, April 14, 12
3. 我本來是個 XXX Developer Saturday, April 14, 12
4. 直到我膝蓋中了⼀一箭... Saturday, April 14, 12
5. 但是 Saturday, April 14, 12
6. 今天不是要來打臉的 Saturday, April 14, 12
7. Let’s take a look at PHP from Perl. 從 Perl 的角度來看 PHP Saturday, April 14, 12
8. Language Saturday, April 14, 12
9. PHP Saturday, April 14, 12
10. Rasmus Lerdorf 於 1995 年發明 PHP Danish Programmer Saturday, April 14, 12
11. PHP3 Zeev Suraski Andi Gutmans Zend Technologies Saturday, April 14, 12
12. A general-purpose server-side scripting language 伺服端的腳本語言 Saturday, April 14, 12
13. A general-purpose server-side scripting language 伺服端的腳本樣板語言 Saturday, April 14, 12
14. 動態產生網頁內容 Saturday, April 14, 12
15. PHP • 從 C 語言 CGI 函式庫發展 • 以早期 Perl 的部分語法為雛形 • 2002 年 PHP 4.3.0 新增 CLI SAPI • 2004 年 PHP 5.0.0 新增類 Java 的物件模 型 • 2012 年 PHP 5.4 引進 Trait, 內建 Http Server, 大量改善 Zend Engine 效能 Saturday, April 14, 12
16. Perl Saturday, April 14, 12
17. Larry Wall 程式員, 系統管理員, 語言學家, 作家 1987 年發明 Perl Saturday, April 14, 12
18. There's More Than One Way To Do It. 不只⼀一種方法來做⼀一件事情 Saturday, April 14, 12
19. 為了「...」而設計的的 Perl “When Larry designed the first Perl, he was a sysadmin, Perl was designed for sysadmins. When Perl5 was created, Larry was a programmer. Perl5 is designed for programming. It is a programming language. Larry is now a language designer, Perl6 is a language for language design.” - Jesse Vincent from gugod http://gugod.org/2011/11/perl-for-dot-dot-dot/ Saturday, April 14, 12
20. Perl: 以簡馭繁的中心思想 <?php $list  =  array_map(function($item)  {                                  return  $item  .  'bar';                        },  array_filter(  $list,  function($item)  {                                  return  preg_match('#^foo#',$item);                        }); Saturday, April 14, 12
21. Perl: 以簡馭繁的中心思想 <?php $list  =  array_map(function($item)  {                                  return  $item  .  'bar';                        },  array_filter(  $list,  function($item)  {                                  return  preg_match('#^foo#',$item);                        }); #  perl @list  =  map  {  $_  .  'bar'  }  grep  /^foo/,  @list; Saturday, April 14, 12
22. Perl • 從 Unix scripting language 出發 • 借取了 C, sed, awk, shell 等特性 • 1990 年時大量 CGI 程式使用 Perl 寫作 • 1994 年 Perl5 加入 OOP • 5.8.0 版時加入了 Unicode 支援 • 2006 年第⼀一版 Moose 模組 (後現代物件系統) - 可改 善 Perl 的物件導向功能，包含 Trait, Lazy Attributes 等 功能 • 2009 年 Plack 模組的出現使得 Perl 於 Web 開發上效 能、便利性更是大大提昇。 Saturday, April 14, 12
23. 小結 • PHP 在語言設計上，除了 server-side scripting language 外並無明顯的中心思想 • Perl 以命令列發展至 Web，而 PHP 是後來才加 入了命令列支援。 • 類別自動載入機制，是在 PHP 5.x 版後才加 入，因此多數 PHP 模組載入方式、路徑格式差 異相當大，也使得各系統間元件相當難重新使 用 (reuse) Saturday, April 14, 12
